A bootstrap drive circuit, a motor controller, a compressor, and a vehicle are provided. The bootstrap drive circuit includes a bootstrap unit, a negative voltage unit, a drive unit, and a voltage stabilization unit. The bootstrap unit is configured to provide the voltage stabilization unit with a bootstrap voltage. The voltage stabilization unit is configured to perform a voltage stabilization processing on the bootstrap voltage to output a stable drive voltage to the drive unit. The drive unit is configured to drive, in response to receiving a turn-on control signal and based on the stable drive voltage, a switch tube corresponding to the drive unit to be turned on, and to control, in response to receiving a turn-off control signal, the negative voltage unit to drive the switch tube to be turned off by generating a stable turn-off negative voltage based on the stable drive voltage.
